S Claims. V(Cl. 210-7'6') This invention relates Ato improvements -in centrifugal eX-fr'atols S'ed fr Ethe treatment "O'f ile rn'afrial.

I'heinve'ntion 'r'ela't'e'spa'r'ticul ly'to'na' angement for restraining 1movement 'of 'pack ges of te'ittile material beiiigitrleatedin aee'n-triiugal extractor. V

YWhenfoakes, skeins, cheesesponthe like,'of textileyarn or -f-tlirea'tl 'are treated `in a centrifugal extractor, it is customary to pile 'the Apackages offtex'tile material, uniforrily distributed, in annular piles, lgenerally adjacent tothe inside'of thevperforated sidewall of the basket 'ofthe centrifugal extractor. l

When an extractor so loaded is rotated at high speed to remove 'water or'other liquid 'from th'epackages of textile material, the centrifugal force tends to cause the textile material to move `toward -th'e-fsidewall'of `the perforated basket. As `a result the dimensions of thepackagesprp'endicular to'thesidewall of thetpe'rforate'd basket tends to become'reduceiwhich `in turn causes the other dimensions of -th'epackages to become v-cc` rr`espondin'gly increased. yAs a fu'rthe'r result, 'the packages A`of textile material, especially the topmost, 'tend to 'turn so as lto bring their smaller Ldimension perpendicular'to 'the side- Wall-ofthe-perforatedbasket.

This deformation and shiftingof-th'e'pacakaiges of-tex til'e material tends to -disarrange '-the 'thread fstructure of the :packages vto y'such -an extent that ywhen lthe Vthread is Wound voff instead of running smoothly it `tends to pluck and break at thefdisarran'gedplaces.

lt is therefore an `object of this invention lto Aprovide a devicevto-be placed over the'annular piles-of packages of textile material being ftreated in a centrifugal extractor-to restrain movein'enttof the individual packages.

ltfis a furtherobject of the invention to provide guide means for the package restraining `device and adjustable means whereby the restraining device `may be held in 'engagement Awith the tops of the annular'piles of packages'of textile material.

It is a still further object of the invention to provide means for raising the `device adapted to restrain `movement of packages of textile material in a centrifugal extractor so asto permit inserting or removing thefpackagesiof textile material-piled in the-perforated basket.

yA device -of-the type contemplated bythis invention is shown in the drawings,in which:

Fig. 4 is a plan View of a package restraining device; and

Fig. 5 is a fragmentary vertical section along the line 5 5 showing means for holding-thepackagerestraining device in engagement with -the tops of the annular piles Vof .-packages.

The centrifugal lextractor shown in 'the drawings 'consists of a curb 'or casing `1 provided with a'liinged cover 2 yadapted `toelose the Atop'opening thereof, and a bottom portion 3. Adapted "to rotate within thel-curbp'or ca'sing 1 is'a perforated basket f4, lthe Ilbottom -of which 'has a coniclly shaped portion 5 secured to lthe shaft 6 which rtat'e's yin `tlie bearings `7 provided in the bottom 3.

A motor lil, attached to the curb or f'cas'ing ='1by suitable "means, -is connected with the shaft *6 by means 'of a `=belt 9. The curb or casing "1 -is provided with supporting lugs y1'0 yto xwhich lare attaeheti suspension -fr'ods 24 and springs 12 Whichfareadapted to minimize vibration when the centrifugal-extractor is running. The 'rods Z4 are in turn attachedltofs'uppr'ting 'standards T13 rspaced about the curb or casing. The liquid removed from fthe textile material treated in the :centrifugal y'e'.xtra'ct'or 5may be `drawn ff fth'reugh 'the drain zofattachei 'to the bottom ofthe casingil.

The perforated Vbasket-2lfin'whichfthe packages of textile material Z1 are inea-ted is :provided with a 'nat 'generally annular device 14, which `fnay y'beinadefof-stainless steel or othersuitable material, of isuch size that itwillIf-al'rnost completely t' cover ithe 'annular i piles of packages of textile material 21 'in said perforated fbasket, while 1stllllleavinfg the center 4of -the 'basket open I and 'relativelytundbstructed forthe insertion andremovalLofasaid'packages. If'the perforated basket :is provided 'with =a flip v15, it vwill "be necessary -tha't the flat .generally `:annular device 121 'be made-in -two 0r-mo`re parts and lassembled by lrifvetin'glor other suitable means (as shown in Fig. 4) after itislplaced in positien'in the'` perforated ibasket.

The=fatsgenerally annular device f14 is mountedona plurality of tguide -r'ods 16 which :pass through the holes 22 2in the -device 114, 'and arefattached xto the'lip 15 :and to .the bottom -of the E*perforated 'basket 4. lThe guide rods -il6are-threaded at one e'nd in order-that th'eymay be screwed Sinto-threaded holes in'thebottorn of thegperforated Vbasket '4, and are of such length that whenpassed through nthe openings in the lip -1'5 andscrewedtinto the bottom `of the ,perforated basket A4, their -upper'ends `will extend slightly A`above the lip. This sim-ple -method `Vof mounting theiguidemods-facilitates assembly-.ofthe :device and 'providesrm-support fortherods.

` The guide rods -16 arezprovided with-atpluralityoftholes 17 through which ,pins 18 may `be Vpassed Eto tlimitlthe upward movement .of `the ilat generally annular device i4, asshown in detail inthe fragmentary -verticalfsection in Fig. S. The .pins 118 are Vsecuredfloosely#toItheflat generally annular device 14 by chains-23 so 'as :to avoid loss or misplacement of the pins.

The vertical guide rods 16 maybe .provided with-coil springs All9y of suilcient strength to cause 'therilat genezrally annular device'14, when not restrained by theipins 18, 'to move Vupwardly so as -to permit linserting and removing packages of textile material "21 through the annu'la'r device `14. The upward movement of the llat generally annular device 14 is limited 'by lip IS of ytheperforated basket'4.

In operation the hinged cover '2 is swung to-the open position and the pins 1'8 are-removed .from the zholes 17 'in theI vertical 'guider 'rods 16 sos Vto permit y'the coil springs 19 'to lift Jthe nat generally Y@laminar .device "1`4 alongth'e vertiealfguitierods "1'6 towardsil'ipls f tlieperrotated basket 4. rThecentrifugalextractor is now-'ready ttybe l loaded, lwhich "is vace'ornplis'heu `bypl'ac'i'ng 'adjacent to are yinside-eftlietperrorated wall 'of thebasket, as"'un'iiq1-rniy aspossil5le about the wall, oneormere annular pfleger-cakes, -skeinsrer "the like, 'of ytextile material. Fig. 1-1shows a centrifugal extracterywithitneiat 'generally Aannu-lar device "14 raised by/coilv springs 19, ptly loaded ywith "packages ef textile material.

-fterthe 'centrifug'lextractor is 'loaded withpackages of textile material the flat generally annular device 14 is forced down against the tops of the piles of packages of textile material 2.1 by hand or by means of a suitable lever and the pins 18 are placed in the holes 17 in the vertical guide rods 16 so as to hold the at generally annular device 14 firmly against the tops of the annular piles of packages of textile material 21.

When the motor 8, acting through the belt 9, causes the perforated basket 4 to rotate rapidly so as to remove water or other liquid from the packages of textile material, the flat generally annular device 14 restrains the packages of textile material so that they do not move about or become deformed. As a result the thread structure of the package is not deranged and the later winding off of the thread is facilitated. Damage to the thread, caused during winding off when a deranged package structure suddenly increases the tension on the thread, is avoided.

After the hydro extraction of the textile material has been completed, the motor 8 has been stopped, and the perforated basket 4 has come to a complete stop, the hinged cover 2 is swung to the open position and the pins 18 are removedfrom the holes 17 in the vertical guide rods 16. The coil springs 19 thereupon cause the liat generally annular device 14 to move upwardly along the vertical guide rods 16. The packages of textile material may be removed from the perforated basket 4 through the opening in the flat generally annular device 14.

It will be obvious that the package restraining arrangement of this invention may be adapted to the various I types of centrifugal extractors known to the art and to the treatment of the various types of packages of textile materials.

For example, if a perforated basket has no lip, or if A the lip is not of suicient width to support the vertical guide rods in the desired position, suitable brackets may be provided to support the vertical guide rods at points beyond the lip. On the other hand, in such a centrifugal extractor, it may be desired to have the vertical guide rods supported only at the bottom. In such case, if the perforated basket has no lip, it will be possible to make the iiat generally annular restraining device in one piece. If the vertical guide rods are not supported at their tops, the coil springs will obviously be adapted to move the at generally annular device upwardly only to a point somewhat below the tops of the vertical guide rods.

The coil springs on the vertical guide rods may be omitted and the package restraining device raised by hand. If the coil springs are omitted it will be necessary to provide some means, such as hooks engaging the top of the basket for holding the package restraining device in a raised position while loading and unloading the extractor basket.

The package restraining device is shown in the form of a flat generally annular structure. The size and shape of this device may be varied as long as it will almost completely cover the annular piles of textile material in the extractor, while still permitting ready access for insertion and removal of the packages. The package restraining device will obviously be sufciently rigid so that it will not become deformed while in use.

Centrifuges provided with the package restraining device may also be used for the wet treatment of yarn packages. The package restraining device will serve to prevent displacement or other disturbance of the yarn packages by the treating liquid, or by the spray, if such is used, as well as to compact the packages into a uniform mass adapted to be rapidly and uniformly penetrated by the treating liquid. While the basket 4 has been illustrated in the drawing as a perforated basket, it may be made Without perforations. Instead, the side walls of the basket 4 may be made of sheet metal having small vertically extending corrugations, so as to provide small vertically extending channels which will not be sealed by the cakes and which will readily remove the liquid out of the i cakes 21 by centrifugal action. lf desired, the diameter of the top of the basket may be made somewhat greater than the diameter of the bottom of the basket so as to facilitate draining of the liquids from the basket by centrifugal action. It is of course obvious that suitable vertically extending grooves may be provided to the inside walls of the basket 4 in place of the corrugations for the same purpose. Furthermore, suitable holes must be provided around the top peripheral edge of the basket 4 at the top ends of the corrugations or grooves so that the liqud extracted from the cakes may be ejected from the basket during rotation thereof.

Other modifications of the invention will be obvious to those skilled in the art and it is not desired to limit this invention to the exact detailed structure described and illustrated except as defined by the claims.
